Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.

Biliary and Pancreatic Sphincterotomies for Sphincter of Oddi Dysfunction

This 43 year old woman has severe recurrent RUQ pain post cholecystectomy. Liver and pancreatic chemistries and duct size are normal, but pancreatic manometry is abnormal. The plan is to perform dual biliary and pancreatic sphincterotomy. The pancreatic duct is cannulated with a 3.9 French tip tr...iple lumen papillotome loaded with a 0.025 inch Jagwire. Contrast is injected to outline the course of the duct. The wire is passed to the tail. Notice the knuckling of the wire into the tail. This provides a safety loop, but is only safe in a small duct with use of a smaller caliber wire. Then with the wire securely in PD, papillotome is used to cannulate the bile duct. Placement of the wire in PD guarantees access for pancreatic stent placement, which is mandatory in these patients to reduce risk, it also facilitates difficult biliary cannulation. Here is the fluoroscopic view as the papillotome is passed deep into bile duct. This shows wires in the CBD and PD. Now a biliary sphincterotomy is performed, with the pancreatic guidewire in place beside the papillotome. The scope is pushed into a longer position to orient up the middle of the papilla. The sphincterotomy is done in very careful stepwise fashion to avoid perforation. Now the biliary wire is removed and the papillotome passed over the pancreatic wire for pancreatic sphincterotomy. The incision is aimed back up towards the biliary sphincterotomy to ensure the septum only is cut. Note the large pancreatic orifice. Last, a 4 French 9cm unflanged soft material pancreatic stent is placed. We always use single pigtail design to avoid inward migration of the stent. The long unflanged design allows spontaneous passage within a few weeks.

Meniscus allograft survival in patients with moderate to severe unicompartmental arthritis: a 2- to 7-year follow-up.PURPOSE: We present meniscus allograft survival data at least 2 years from surgery for 45 patients (47 allografts) with significant arthrosis to determine if the meniscus can survive ...in an arthritic joint. Type of Study: Prospective, longitudinal survival study. METHODS: Data were collected for 31 men and 14 women, mean age 48 years (range, 14 to 69 years), with preoperative evidence of significant arthrosis and an Outerbridge classification greater than II. Failure is established by previous studies as allograft removal. No patient was lost to follow-up. RESULTS: The success rate was 42 of 47 allografts (89.4%) with a mean failure time of 4.4 years as assessed by Kaplan-Meier survival analysis. Statistical power is greater than 0.9, with alpha = 0.05 and N = 47. There was significant mean improvement in preoperative versus postoperative self-reported measures of pain, activity, and functioning, with P = .001, P = .004, and P = .001, respectively, as assessed by a Wilcoxon rank-sum test with P = .05. CONCLUSIONS: Meniscus allografts can survive in a joint with arthrosis, challenging the contraindications of age and arthrosis severity. These results compare favorably with those in previous reports of meniscus allograft survival in patients without arthrosis. LEVEL OF EVIDENCE: Level IV.

LIZ: The first time the doctor made my tip too narrow and I didnt look like myself. The second time the doctor made my tip too wide, and actually took out (removed) extra bone from the side of my nose. That didnt need to be taken out (removed)

My initial consultation with Dr. Nassif was fantastic! He treated me liker his own daughter, and was very caring and thorough. He went over everything!

DR. NASSIF: Liz came into me for a revision rhinoplasty. She told me that shes had two previous rhinoplasties. She was unhappy with the way her nose appeared on her face. She felt it was asymmetric, the tip was kind of bulbous, or large appearing, especially when she looked up, this view, it was very asymmetric. And so, her whole goal was to make it look better, hopefully make it her LAST surgery, and also to help with her breathing.

One of the things thats very important about revision rhinoplasty that you always have to consider is; What are you going to find in there? Even though you can feel the nose, you can palpate it, you can look at it, and you can guess what the other doctors have performed; your first up-hill battle is to see how much scar tissue youre going to be able to identify with. So when you have to open up the nose, you have to remove the scar tissue, identify it: whats there, whats present, whats been removed. Then after you do that, and you have cartilage now ready for grafting, or fascia, or perichondrium, you have to start rebuilding it. Rebuilding it (cartilage) is the second big stage after weve already carved everything; weve carved the cartilage. In that scenario when Im playing with the nose, in regards to staring at the profile, staring at the front of the nose, I go back and forth and look inside and outside of the nose to make sure its as symmetric as possible. That takes a long time One of Lizs main complaints was that on her profile, that her tip stuck out too far. And so one of the things I had to do in surgery is called a medial cura tuck-up, I had to push the tip back, by pushing the tip back, it can make the tip look a little bit wider. But in this situation, I was able to bring everything in as much as I can. After Im finished with everything, and Im happy, then we go ahead and we start to close the nose. Thats putting every little small stitch in perfectly, so that the scar will be minimally visible.
